IMPROVEMENT IN CORN-HARVESTERS.

Specification forming part of Letters Patent No. 176,095, dated April 11, 1876 application filed June 17, 1875.

To all whom it may concern:

Beit known that I, WLLIAM H. TAYLOR, of Toledo, in the 4county of Lucas and State of Ohio, have inventedan Improved Gorn- Harvester, of Whichthe following is a specification:

The nature of my invention relates to al1 improvement in corn-harvesters of that class wherein the cutting ofthe stalks is effected by revolving disk-knives; and it consists in the various combinations, all as more fully hereinafter set forth.

Figure 1, Sheet 1, is a perspective view vof the harvester. Fig. 2is a plan of the same. Fig. 3, Sheet 2, is a sectional elevation taken on y y in Fig. 2. Fig. 4 is an elevation of the gear on the inner side of the driving-wheel. Fig. 5 is a plan of the drivin g-shaft and its gearing, and a horizontal section in the same plane of the drive-wheel. Fig. 6 is ahorizontal section at om in Fig. 3. Fig. 7 is a transverse vertical section through the stalk-cutters at c z in the last figure.

In the drawing, A represents a platform, having at its right rear corner a projecting arm, upon which is mounted a traction-wheel, B. From the left side of the platform a long axle A' projects, with a traction driving-wheel B' mounted on its extremity. G is a drivel-s seat mounted on this axle. D is the drivingshaft, obliquely journaled through a bracket projecting to the rear from the axle A', and in a bea-ring at the inner rear corner of the platform. E is an internally-toothed spur-gear on the inner face of the driving-wheel, and gives motion to a pinion, E' sleeved on the outer end of the driving-shaft, which is putin motion by a pin, a, on the hub of the pinion engaging with a clutch, a', feathered on said shaft, and which is thrown into gear by a spring, b, behind it. The shaft is unclutched and thrown out of gear by a lever, c, actuated by another lever, c1, at the side of the driver-s seat, to which is pivoted a latch, c2, for locking it.

The platform is longitudinally divided into two parts set close together, each half being tapered on the inner edge, making an acute angular throat. The right end of the platform slopes downward like the shoe of a harvester, while the left front end is curved up Ward. The machine is drawn so that the row of standiu g corn will be embracedin the throat referred to.

F is a vertical metal guide-plate extending along the left edge of the throat in the platform, curving thence to the left rear corner thereof'. F' is a sideboard extending along the right edge of the platform. G is a chordbar about mid-height of the plate F, projecting horizontally beyond it in front, and has the left front end of the platform secured to it. Its rear end extends through a horizontal slot in said plate, and turns up behind it. Gl is a bar extending from the barG horizontally to the 'left parallel with the axle in front thereof, and is connected thereto by a curved bar, G2, to constitute the main frame of the machine, the draft-tongue of which is secured to the bar G1. H is a bevel pinion on the inner end of the driving-shaft, which meshes with a similar pinion, H', to give motion to a vertical shaft, I, on which it is keyed, the said shaft being stepped on the adjacent corner of the platform, and journaled up through abracket projecting from the chord-bar G. J is a diskcutter, sleeved on a stud on the right side of the platform in such a position as to reach over to the left of the center of the back part of the throat in said platform. J' is a cuttingwheel composed of two superposed disks, which receive the edge of the single-cutter disk between them. The double-disk cutter J' is mounted on a vertical shaft, K, stepped on the platform out-side of the guide-plate F, and is fitted with a ian ged pulley, L, near the upper end, which receives a belt, M, from a flanged pulley, L', on the shaft I, whereby the double-disk cutter is rotated, so as to cut the stalks of standing corn coming in contact therewith. N is a chain-wheel at the top of the shaft I. N is a flanged Wheel at the top of a vertical shaft, O, stepped on the front end of the chord-bar G. P is an endless chain running around the flanged wheels N N', and around the inner faceof the guide plate F. The chain is made up of two sets of parallel links pivoted at the ends of the links by transverse bolt-s. Every third pair of link-bars has a bell-crank arm, Q, pivoted at its angle to the center of the link-bars, the shorter arm lying, behind the next link-pivot bolt followingit. i

By this arrangement the arms can be folded back on the side oi' the chain next the driver; but as soon as the short arms come against the face of the chain-wheel N they are thrown around so as to bring the longer arms .on a radius, following the radius of the inner ,face ofthe guide-plate as the chain moves back, thereby sweeping the standing corri-stalks to the cutters, and carrying `them along after they are cut.

A post, It, at the side ot' the drivers seaty folds back 'therarms as they s weepbyphim.

At the lip-turned rear end of the ehordfbany Gr there is a horizontal T-rest, S, havingpiv` oted to its right end a pair of crossed-arms,I T. Through its lef'tend `passesa latch-bolt, U,shot.back by'a spring. The frontend .of this boltlis pivotedlto aleyer, U(,.vto thcright, ot' the drivers seat. The bolt normally projects intothe plane of the `arms ,'l, and pre! vents them from turning vtoward kthe right. rlhe c. rnstalks-fall on the right horizontal arm, and when a gavel accumulates .thereon the driver discharges vit Vby withdrawing :theA latch-bolt and allowing the arms v'J1 tomake. a quarter revolution.
